CDK Inhibitor

Daphnoretin (Dephnoretin; Thymelol) is a protein kinase C (PKC) activator that inhibits the expression of hepatitis B virus (HBV) surface antigen (HBsAg) and exhibits antiviral activity. Daphnoretin exerts its antitumor effects by inhibiting the activation of the PI3K/AKT signaling pathway and triggers the mitochondrial apoptosis pathway. Daphnoretin alleviates chondrocyte apoptosis and inflammatory responses by inhibiting endoplasmic reticulum stress and activation of the NLRP3 inflammasome. Daphnoretin regulates the differentiation and maturation of dendritic cells, inhibits their immunostimulatory function by downregulating the phosphorylation level of JNK, and thus exerts a protective effect in skin graft rejection.
